Usually I only place lottery bets, in 24 hours I place 4 lottery bets in different markets and it doesn't take long for me, because I only open them when placing bets and betting results.
Hope you have not got addicted to this lottery bets because even you would be knowing how many people play those bets and how many are going to win it. Just always do one thing that in the month end just total bets placed and money spend on those lottery and if any return you got it or not will give you a clear picture.
